Product Description
Sprocket 08B-1 z=37, hardened hub
Sprocket 08B-1 (pitch 1/2" - 12.7 mm), simplex, 37 teeth, with hardened hub. Compliance with DIN 8187 / ISO 606 guarantees full interchangeability with chain of the same pitch; C45E steel (EN 10083-1) and induction hardening of the teeth (45-55 HRC) provide high wear resistance while keeping the hub machinable.

Frequently asked questions
Can a sprocket with a technological bore be installed without additional machining?
No - the technological bore is deliberately too small to fit a typical shaft. It must be bored on a lathe to the required diameter and, if necessary, a keyway cut according to the requirements of the specific machine.
What does the pitch of a sprocket mean and how can it be checked?
The pitch of a sprocket corresponds to the chain pitch - it is the theoretical distance between the centres of adjacent teeth on the pitch circle. The easiest way to check it is to place a section of matching chain on the sprocket - it should sit perfectly, without tension.
How do you cut a keyway in the hub of a sprocket?
We cut keyways precisely on slotting machines according to DIN 6885. If you do it yourself, maintain axial alignment and the correct width and depth of the keyway so that the key sits securely and is not sheared off.
When does tooth wear (the "shark fin" profile) mean the sprocket must be replaced?
If the teeth resemble pointed, tilted shark fins, the sprocket must be replaced immediately. Operating on such a profile can damage even a brand-new chain within a dozen or so days.
Where is this product used?
08B-1 sprockets operate in the drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under heavy load matters.
